Hello, 
  we have a client with AIX version 7.1 what is using PostgreSQL 9.3.5 compiled with GCC 4.6.4 wonder if it's appropriate or would you rather use the XLC to obtain a better performance?

Regards

IMHO most of the performance for a database is I/O related and a
result of the layout and the application. Code optimizer may result in
some low one digit percentage changes, so no need to optimize for most
cases.
